Conjoined lexical units

A single surface form can correspond to multiple lexical units. When this happens, the lexical units are connected with +.

An example of where this might be useful is English plurals and possessives:

^dog/dog<n><sg>$
^dogs/dog<n><pl>$
^dog's/dog<n><sg>+'s<gen>$
^dogs'/dog<n><pl>+'s<gen>$

In monodix this is written with <j/>

<pardef n="dog__n">
  <e><p> <l></l>    <r><s n="n"/><s n="sg"/></r>                   </p></e>
  <e><p> <l>s</l>   <r><s n="n"/><s n="pl"/></r>                   </p></e>
  <e><p> <l>'s</l>  <r><s n="n"/><s n="sg"/><j/>'s<s n="gen"/></r> </p></e>
  <e><p> <l>s'</l>  <r><s n="n"/><s n="pl"/><j/>'s<s n="gen"/></r> </p></e>
</pardef>

<e lm="dog"><i>dog</i><par n="dog__n"/></e>
